AIR COMPRESSOR OR MOTOR.

Specification of Letters Patent.

Patented Sept. 8, 1914.

.Application led October 2,4, 1913. Serial No. 796,999.

To all whom t may concern:

a citizen of the United States, and a resident of New York, borough of Manhattan, in j the county of New York and State of New; York, have made and invented certain new; and useful Improvements in Air Compres-i sors or Motors, of which the following is a' referred to the device as a whole; and, Fig.

specification.

My invention relates`to air or gas com?y pressors, air operated motors, fluid operated:` engines, etc., that is, to devices capable of use either as a pump or compressor, or as.`

an engine, and particularly to that type of compressor in which a cylinder member having a lplurality of radiating cylinders rotating about a stationary valve member is employed.

Compressors of the type above referred to employ a reciprocating piston in each separate cylinder` and the object of my inven` tion is to provide, in such a compressor or engine, improved mechanism for imparting reciprocating motion to the pistons as the cylinder member is rotated, or for converting the reciprocating motion of the pistons into rotary motion of the cylinder member and a driving shaft.

Vith the above and other objects in view, my invention consists in the improved pump or motor construction illustrated in the accompanying drawings and hereinafter described and claimed, and in such variations and modifications thereof as will be obvious to those skilled in the art to which my invention relates.

In the drawings wherein the preferred embodiment of my invention isk illustrated: Figure 1 is a view showing a section of my improved motor or pump upon a vertical transverse plane indicated by the broken line 1-l, Fig. 2; Fig. 2 is a view showing a section upon a horizontal plane indicated by the brokenline 2-2, Fig. 1; Fig. 3 is f a view showing a section upon a vertical transverse plane indicated by the broken .line 3-3, Fig. 2; Fig. 4 is a fragmentary view showing a section upon a vertical transverse plane indicated by the line 4 4, Fig. 2; Fig. 5 is a similar view showing a section upon a vertical longitudinal plane indicated "by the line 5 5, Fig. 4, looking toward the left; Fig. 6 is a' view similar to Fig. 3, but showing the parts in another position; Fig. 7 is a view showing the valve member of my device as seen from a position `with the pistons above referred to.

v j to the left of Fig. 5; Fig. 8 is a view'show- Be it known that I, WILLIAM A. WARMAN,

ing .the valve member in side elevation; Fig. 9 1s a view showing said member in plan; Fig. 10 is a view showing one of four eccentric disks employed in the form of my inven` tion illustrated; Fig. 11 is a view showing an eccentric strap and yoke forming a part of my device assembled and in end elevation,

12 is a view showing said elements in side elevation.

Referring to the drawings, the reference numeral 15 designates two similar parts of an external casing within which the 'operat ing parts of my improved pump and motor are contained, 16 designates a stationary valve member supported fromv said casing,

and 17 designates a bearing also supported from the casing and through which the shaft 18 extends, which shaft, as will be understood, serves as either a driven or a driving shaft, with reference to external devices, according to whether my device is used as a pump or as a motor. The valve member is provided with suitable inlet and discharge passages 19, 20, assuming the deviceto be used as a compressor. Located Within the casing aforesaid and rotatable about the stationary valve member is a cylinder mem ber 21 having a plurality of radially extendlng cylinders, four such cylinders 22, 23, 24,

' 2.5 arranged at right angles to one another being employed in the embodiment of my invention illustrated. NVithin each cylinder is located a reciprocating piston to which the reference numerals 26, 27, 28 and 29 are applied. The cylinders and pistons are preferably made comparatively long with reference to the stroke, so as to avoid the necessity of separate meansv for guiding the pistons in their movements, the cylinder walls forming the necessary guiding means.

The mechanism whereby reciprocating motion is communicated to the pistons as the `cylinder member 21 rotates comprises two stationary eccentric disks 30, 31 shown as secured to the valve member 1G by means of screws 32, the relative position of the disks being such that the pistons 2G` 2S in two oppositely located cylinders, see (Fig. 3, will be moved simultaneously in opposite directions as the cylinder member rotates; and two eccentric straps 33, 3i surrounding said disks and which straps are operatively connected other pistons 27, 29 are operated by means of 'The 'I two operating members 35, 36 shown as in the form of yokes having a central opening large enough to clear the eccentric disks and straps when the device is in operation, one

end of the yoke 35 being pivotally connected with the strap 33 at 37, while the yoke 36l is connected in a like way with the strap 34 at 38. The outer ends of these yokes are operatively connected with the pistons 27, 29,

see Fig. 3, from which construction it willl be obvious that said last-mentioned pistons-v Will also be moved simultaneously in opposite direction as the cylinder member 21 rotates.

I prefer to duplicate the operating mechanism above referred to upon the side of the cylinder member adjacent the bearing 17 in order that the force acting upon the pistons may not tend to tip them and cause unequal wear, or binding in the cylinders. Thus the reference numerals 39, 40, see Fig. 2, designate eccentric disks similar to the disks 30, 31 and similarly arranged, which disks are secured to the bearing 17 by means of screws shown in dotted lines.

The numerals 41, 42 designate yokes similar to the yokes 35, 36, and the inner ends of which are pivotally connected with the eccentric straps 43, 44 which surround the i disks 39, 40. The outer ends of the yokes 35 and 41 are secured to across bar 45 carried by the piston 27 and, as the said yokes move simultaneously in the same direction, it will be seen that the ends of the bar are' 'subjected to equal pulls, and that force is transmitted to the piston along its center line. In like manner the free ends of the yokes 36, 42 are connected with the piston 29 through a cross-bar 46. lIt will be understood that the eccentric straps 43, 44 are connected with the pistons 26, 28 in a similar way, and act in connection with the straps 33, 34 to operate said pistons. Although such connections are not actually shown, the upper and lower free ends of the straps 43, 44 lie back of and are hidden by the straps 33, 34, Fig. 1, as will be understood from Fig. 6 in which the greater part of the dii-- plicated operating mechanism located adja- 4cent the bearing 17 appears in dotted lines,

as itlies be ond the rotating cylinder member appearing in that figure. The main shaft 18 is operatively -connected with the rotating cylinder member 21 in any Way as by means of a flange 47 secured to said member by suitable screws. Such being the construction of my improved'motor or pump, it will be seen that as the cylinder member rotates, the pistons in each pair of oppositcly located cylinders will move simultaneously toward and from one another. Thus, referring to Fig. 3, and assuming the device to be used as an air compressor, and renieinbering that the corresponding position of the piston operating mechanism 1s as is illustrated in Fig. 1, rotation of the cylinder member in the direction indicated `by the arrow will be accompanied by a simulta-' vided in the valve member and a passage 50 into the discharge passage 20 of the valve member. At the same time air will be discharged from the cylinders 24, 25, see Fig. 4, through ports 51 in the cylinder heads, and through a recess 52- provided in the valve member and a passage 53v into the discharge 20 of the valve member. The discharge recesses 49 and 52 are oiset from one another, as shown in Figs. 2 and 9, and the views shown in Figs. 3 and 4 are upon diierent planes, as hereinbefore explained.

fAfter the cylinder member has been rotated through 18()o the various parts will occupy the positions shown in full and in dotted lines in Fig. 6, and all the pistons will move outward as the cylinder member continues its rotation. Upon further rotation in the direction indicated by the arrow, the ports 51 in the cylinders 24,' 25, see Fig. 4, will communicate with a recess 54 in the valvemember, which recess is in communication with the supply or inlet passage 19 through a assage 55, and air Will fiow into these cylin ers. At the same time the ports 48 in the cylinders 22, 23, see Fig. 6, will communicate with a recess 56 in the valve member, which recess is likewise in communication with the inletv passage 19 through a passage 57, and air will alsoflow into these cylinders. The supply recesses 54, 56 are offset in the same manner as the discharge recesses 49, 52, see Fig. 9, the supply and discharge recesses being located opposite one another, as sho-wn in Figs. 2, 8 and 9, and separated b Walls 58 as will be understood.
